SPECIFICATION forming part of Letters Patent' No. 698,303, dated April 22, 1902.

Application filed November 2| 1901. Serial No. 80,900. (No model;

To @ZZ whom it may concert/LL v Be it known that 1,J OSEPHMIOHALKA, a citizen of the United States, anda resident of Cameron, in the county of Milam andY State of Texas, have invented, newand useful Im-` provements in Shovel-Flows, of which the following is a full, clear, andl exact description.v

This invention relates to certain improvements in shovel-plows by means of which the l stock and shoe may be securely mounted and yet adjusted from one position to anotl1er,ac cording to the work to be performed.

This specification is a specific description. of one form of the invention, while the 'claims' are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in'all the views.

Figure 1 is .a .side view of the invention. Fig. 2 is a section on the line 2 2v of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. 1. a indicates the beam of the plow. The stock is preferably made up of two dat side pieces b, fastened rigidly together by staybolts b' and lying one on each side of the beam a, with the stay-bolts respectively above and below it.

c indicates a forwardly and downwardly projecting brace fastened to the under side of the beam and extending between the side plates b of the stock. This brace carries the pivot-pin b2, whereby the stock is mounted to swing in a vertical plane to adjust the inclination of the shovel, which is carriedon the lower end of the stock. Let into the top of the beam a and running longitudinally thereof is a bed-bar d, the top face ofwhich is arc-shaped concentrically to the pin b2, and over the face of the bar plays theupper bolt b of the stock. Pivoted to the front end of the bar d is a lock-bar e, which iscurved to lie snugly on top of the bar and is formedwith a` notched under face adapted to engage and hold the upper bolt b. Carried .onthe rear end of thebed-bar dis a spring or other catch f for releasably holding the free end of the lock-bar in the position shown by full lines in Fig. 1.

When the lock-bar e is thrown down in the position shown by full lines in Fig. 1, it is held by the catch f, and in this position the lockbar holds rigidly the stock. This latter element'may, however, be freely adjusted by throwing up the lock-bar c. (See dotted lines infFig. 1.)

g indicates the shoe, whichis in the form of a bar extending'longitudinallyunder the beam` a Yand held at the'rear by aileg'h and at -the front by a link i. The leg' his adjustably 6o held to the rear end of the beam ct by means `of a U-shaped plate k, in which the leg fits,

and is held in place to be raised or lowered at will by a pin lo. The bottom of the leg h is notched to receive the foot-bar g, and this bar done by the Various connectionsshown, placing the bar at any elevation or inclination desired.

Various changes in the form, proportions, 8o and minor details of my invention may be resorted fo without :departing from the spirit and scope of myinvention. I-Ience I consider l myself entitledto all such variations as may lie within the scope of my claims.

Havingthus described my invention, I claim as new and desire to secure by Letters Patenti Y 1. Ina plow, the; combination with an intermediately-pivoted stock, of a lock-bar piv- 9o oted at one end and adapted to engage intermediate of its ends a part ofthe stock to lock the stock in position, and means 'for locking the free end of said lock-bar, as set forth.

2. In a plow; the combination-With an" inv termediately-pivoted stock,`of a bed-bar over which a part ofthe stock moves, alock'lbar pivoted vat one end to the bed-bar and'having a locking engagement with the part of the stock which moves over the bed-bar, and roo means for securing the free end of the lockbar in position, as set forth.

3. In a plow, the combination of an intermediately-pivoted stock, and means for adjustably holding the upper end thereof, said means comprising an arc-shaped bed-bar over which a part of the stock moves, a lock-bar pivoted at one end and releasably engaged with said part of the stock, to hold it, and a latch for holding the lock-bar in active position.

4. Inaplow,thecombinationwith the beam, of a stock in two parts lying one on each side of the beam and fastened rigidly together, a member carried rigidly on the under side of the beam to which member the stock is pivoted, and a pivoted locking-bar for engaging a connecting member of thestock to adjustably hold the same.

5. In a plow, the combination of a shoe-bar lying'under the plow-beam, and a means at each end ofthe shoe for supporting it from the beam and adjusting it vertically, said means being adjustably secured to the shoe to permit the shoe to be adjusted horizontally.'

G. In a plow, the combination of a shoe-bar lying horizontally under the beam, means for adjusting the front end of the shoe vertically and horizontally, a leg at the rear part of the shoe to which the shoe is connected to be adjustable horizontally, and a means on the beam for holding the leg and allowing it vertical adjustment.

7. Inaplow,thecombinationwiththebeam, of a brace attached thereto and projecting downward and forward therefrom, a stoel; pivotally attached to the brace and projecting up to the beam, a means on the beam for adjustably holding the stock, a shoe, a link adjustably connected to the front end of the shoe and to the brace, and a leg connecting the rear end of the shoe with the beam.

8. In a plow, the combination with a beam, and an intermediately-pivoted stock carried by the beam, said stock being provided at its upper end above the beam with a cross-pin, of a pivoted locking-bar having a notched under face to engage the cross-pins of the stock, and means for locking the said bar in position.

9. In a plow, the combination with a beam provided with a downwardly and forwardly projecting brace, of a stock pivoted to the brace, said stock being formed of two parts connected together by bolts one on each side of the beam, a bed-bar secured upon the up per face of the beam and having a curved upper face, a locking-bar pivoted to the bedbar and having a plurality of notches in its under face for engaging one of the connecting-bolts of the stock, and a catch for engaging the free end of the locking-bar to lock it in position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
